Isophenilwe methylene isotsanate pu amaphu zokungqinisekisa ngumthetho omncane onguhlakaniphi ophakathi komsebenzi wesikoleni kunye neminyango. Ukhona kwindawo eziqaleni ezininzi ezinikezelayo, zisetyenziswa kunye neziphumeleyo zonke izinhlobo ezinikezelayo. Ngoko ke, ngaphezulu siyafuna ukubuka kule mthetho olungumoya olungumehlo ngokulula.
Methylene phenyl polyol isocyanate kulula ngamabhedheni amaningi, abebe abahlukene abaluleka ukubulawa kwezinto. Amabhedheni amacala kwesiqhovu lencwadi ngu-carbon, hydrogen, nitrogen kunye noxygen. Bahlukene ngenkxaso yobuxoki obunomgomo wokuqala C8H7NO. Lencwadi ifanele njenge umlilo omncedisi okugcineni. Kulula kukhutshwa ngokubanzi ukwenza iipolifomu zepolyurethane, amaphethelo, amaglu kunye neeziseyileyo ezinikezela izinto kunye nokungena
Methylene phenyl polyol kunye no-isocyanate useywa ngemisebenzi eziphathelleyo kwindawo eziningi, kodwa kufuneka uqhoshe ukusetyenziswa kwento yomntla apho akukho. Ukusetyenziswa kweMethylene phenyl isocyanate ungayenza umphulo, izandla, kunye nesiqephu esisethweni, ubuchazele kunye nezinye izincwadi zokugcina. Lendawo lokugcina ungabulala amazinzo amaphatheleneyo njengegqweme, ukungaphelele, ukuba uyikha, kunye nokuhamba kuhle kumhlaba wasembuso. Ukusetyenziswa kokuphela kunye nokuthile kukungenisa imibuzo engakhothayo, futhi kufuneka siyazi iindlela zakuhlola.
Ngokuqinisekanga kwezinyathelo ezifana ne methylene phenyl isocyanate, kuhluke ukuthi uhlalele umthamo omkhulu ngokubheka nokugcina le nkcwakazi. Iziphi zamatsha azozi zikhululeko kufuneka zibe ngonye yezandla, amagogoti aze avale esikhashini nokumaski yokungabophelela izilungu. Ukuphawuliyo okanye lokuvamile kuhluke kukuthi i-methylene phenyl isocyanate ikhangele kwindawo engaphantsi yebhokisi. Yinkulumo enye yokuba kuhluke ukuthi kube ngeventilation encinci njengoba zinto ezingaphansi zizibophelelwe. Kufuneka faka kwindawo engaphantsi yeqhakamasi nokuncedisi zonke izinto ezinokushaya ngendawo.
Ngokubanzi kwezinto ezifunyeneyo ngaphandle kwezichemical zikhe zomthetho, amakhulu nezindaba zazilungiselela ukuba uqondiswa ukuthi zikhona indlela esidingayo. Izindlela ezimbili ezifunekayo zizoba zithathelwa ukukhuphela izinto ezintsha kunye nokusetyenziswa kwesicompound sengxelo. Ukufakelwa lokho kungabangako ukulula ukuthi zihlalele imigomo eminingi kunye nesintsho esinamandla ukusetshenziswa komthetho wokuhlanganisa i-methylene phenyl isocyanate. Isimo esingahlukeleyo sokuhlala kuya kuzo kungu kuthiwa ukusebenziswa kwezi zinto ziqhubeka nokuthi zibheka izindlela ezidingayo ukukholela imiphumulo yesetho kunye nokusenza okugcinweyo ngokwesobizo lwe-chemical. “Ndinga ndiyazi ukuthi yile yi-research eyahlukile, ndiyazi ukuthi sasingene ukwenza izinsuku ezincane ezimemezekayo lapho siyenza uphiko lwesobizo lwe-chemical leyiya phambili.”
